Global Dairy Trade Price Index (GDT)
The Global Dairy Trade Price Index (GDT) is a measure of internationally traded dairy commodity prices determined through a twice-monthly auction. It is particularly important for the New Zealand dollar, as New Zealand is a major global dairy exporter.
Example
“When the GDT Price Index fell 4% at the latest auction, the New Zealand dollar weakened as dairy is one of the country's largest export sectors.”
